' This invention relates to a device for use in linoleum dispensing ordisplay establishments;

pective customer or for cutting off any desired amount from the roll;the latter being then rolled up again, if necessary, before being againlowered to the floor and released from the device.

The device comprises a pair of separate identical units, each adapted toengage and lift one end of the roll, and a further object of theinvention being to arrange each unit so that, while capable of liftingonly one end of a roll, both units may, in turn, be handled by a singleoperator to lift the roll at both ends so as to be clear of and parallelto the floor.

Still another object of the invention is to provide a linoleumk rolllift which is practical, reliable, and durable, and one which isexceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims. f

In the drawings:

Fig. 1 is a front elevation of the device as supporting a lifted roll.

Fig. 2 is a longitudinal enlarged elevation of one unit of the devicewith the roll-supporting spindle, and the actuating handle thereof inlowered position.

Fig. 3 is a top plan view of said unit in the position of Fig. 2 but ona reduced scale.

Referring now more particularly to the characters of reference on thedrawings, the device comprises a pair of roll lifting units l separatefrom and identical to each other and adapted to together support andlift a roll 2 of linoleum therebetween, as shown in Fig. 1.

Each unit comprises a base plate 3 having a rigid post fl upstandingtherefrom centrally between its side edges and intermediate its ends.

Slidable on the post is a sleeve 5 from one side of which a spindle 6projects radially. Freely turnable on the spindle, and mounted on ballbearings B, is a cylindrical sleeve l on which a number ofcircumferentially spaced and outwardly projecting leaf springs 8- aresecured at their ends. The springs are bowed so as to have the greatestextent of projection centrally of the ends of sleeve l, as shown in Fig.2, and the diameter lbetween opposed springs is such that they rolllimiting or locating disc 3 Claims. (Cl. 242-552) will frictionally bindagainst the wall of the central opening 9 in roll. 2 when sleeve 'i isprojected into said opening (see Fig. l). At its end nearest sleeve 5,sleeve l is provided with an enlarged It, rigid with sleeve 7.

'I'he sleeve E, when in its lowest position on the post 4, is disposedso that disc if] just clears the base plate 3, and the sleeve 5 is at alevel such that it may enter the opening t in a roll 2 resting on thefloor onwhich base 3 is disposed. The portion of the base under thesleeve l is cut away, as shown at it, so as to provide laterally spacedfeet i2 which rest on the floor to the side of the portion thereof onwhich the bottom of roll 2 rests, so that the plate 3 may be slid alongthe floor until. the adjacent endof roll 2 abuts the disc Iii, whileproviding such support for the roll lifting unit as will tend to preventupsetting of the unit when supporting the load.

En order to lift the sleeve 'i from said lowest position, a hand leverI3, provided with a rigid grip kIt at its outer end, projects from thebase of post i in a. direction parallel to, but away from, sleeve vl,being pivoted adjacent the post and base on a cross pivot l5 mounted inrigid ears I6 straddling the lever. A pair of links l1 straddle thelever a short distance from pivot l5 and are pivoted at their lower endon said lever, as at i 8. The links extend upwardly at an angle when thelever is lowered, and are pivoted at their upper end, as at i9, on anear 2t] projecting from the adjacent side of sleeve 5 near the topthereof.

When the lever is lifted, the sleeve 5, through the links I1, is liftedalso; the pivot I8 of said links being beyond a dead center line 2ldrawn through pivots I5 and I9 when the lever is lifted to its upwardlimit (against ear 2t) and the sleeves 5 and 'i are correspondinglyraised as high as possible, as indicated in Fig. 2 and shown in Fig. 1.

The sleeve is thus automatically prevented from undesired loweringmovement, but to assure the sleeve being held in such raised position, anotched latch bar 22 is mounted on the lever in position to engage overa pin 23 on one of links I7 when the handle is in such fully raisedposition.

In operation, the units i are initially placed at the ends of the roll 2to be lifted, with their sleeves 1 in lowered position.

If two operators are employed, both units I may be simultaneouslx7engaged with the ends of the roll 2, and the respective handlesmanipulated relatively simultaneously to raise both ends of roll 2 atthe same time.

If one operator is employed, either unit I is rst engaged with one endof the roll 2, and the roll is lifted at said end by manipulation oflever I3. This places the roll 2 at an angle to the floor, and to theaxis of sleeve 1, but because yof the curving springs 8, which are theroll engaging members, said roll can assume an angular position withoutbinding vron the sleeve 1 or tending to bend and possibly fracture.After the one end of the roll has been lifted, the operator similarlymanipulates the other unit i to lift the other end of the roll. n i

As an alternative the springs 8 may be omitted and the outside ofsleeves knurled to provide frictional engagement with the inside of .theroll at the top; the sleeves being of sufficiently lesser diameter thanthe central opening in the roll to permit of initial canting of thelatter as aforesaid.

From the foregoing description it will be readily seen that there hasbeen produced such a device as substantially fulfills the objects of theinvention, as set forth herein.

While this specication sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new anduseful, and upon which Letters Patent is desired:

l. A linoleum roll lift comprising a pair of separate units adapted tobe disposed at opposite ends of the roll, each unit comprising 'a baseplate, a post upstanding from the plate, a sleeve slidable on the post,a horizontal-axis rotary member projecting from and movable with thesleeve and adapted for engagement in one end of the axial opening of aroll, a hand level` pivoted at one end on the base plate adjacent thepost, an upstandingr link between and pivoted at its ends on the leverintermediate its ends and the sleeve, said link being disposed at anupward angle toward the sleeve when the lever is in a lowered positionand the sleeve is in a lowered position on the post, and so that thelever when swung up on its pivot will lift the sleeve and rollsupporting member; the link and the portion of the lever between thebase pivot and the point of pivotal connection of the link therewithbeing substantially alined and vertical when 'the sleeve is fullylifted, and releasable latch means between the lever and link operablewhen said lever portion and the link are in such substantially 'verticalposition.

2. A device as in claim 1, in which the pivot of the link on the leveris beyond a dead center vposition relative to a line drawn through thebase pivot of the lever and the pivot of the link on the sleeve when thelever portion and link are in said substantially vertical position.

3. A device as in claim 1, in which the ,lever projects from the base in-a 'plane parallel to but in a direction away from the rotary member.
